About this site

AdFire Digital is an independent educational resource about one subject: how digital advertising works. It exists because most explanations of paid media are written either by platforms selling ads or by agencies selling services — and both tend to skip the mechanics.

What we publish

Plain-language guides to the machinery of online advertising: how auctions set prices, how search, social and programmatic channels differ, what the standard metrics actually measure, and how a beginner can plan and judge a first campaign. Every term used in the guides is defined in the glossary, and every formula is shown on the metrics page.

Editorial approach

• Mechanics over hype. We describe how the systems work, not why you should spend more on them.
• Verifiable statements only. Definitions and formulas follow industry-standard usage; where a number appears (for example the viewability standard), it reflects a published industry convention.
• No platform allegiance. This site is not affiliated with, endorsed by, or selling anything on behalf of any ad platform, agency or vendor.
• No advertising here. This site carries no ads and sells no ad space, sponsorships or placements.

What this site is not

It is not a media-buying service, an agency, or professional advice for any specific business. Advertising platforms change their interfaces, policies and auction mechanics frequently; always confirm details in the official documentation of the platform you use before spending money.

Corrections

If a definition or formula here is wrong, that is a bug, not an opinion — the guides are maintained to stay accurate as industry standards evolve.
